Question

1. complete the table about solutions, suspensions, and colloids.

solutions, suspensions, and colloids
type of mixture|relative size of largest particles|homogeneous or heterogeneous?|do particles scatter light?
solution|||no

	intermediate	homogeneous
	large		yes

1. circle the letter before each example of a colloid.

a. windshield wiper fluid b. fog
c. homogenized milk d. muddy water

1. is the following sentence true or false? if salt water is poured through a filter, the salt will be trapped on the filter.

Explanation:

1. In solutions, the relative size of the largest particles is small. Suspensions have large - sized particles and are heterogeneous. Colloids have intermediate - sized particles and are homogeneous at a macroscopic level but the particles scatter light (Tyndall effect).
2. A colloid is a mixture in which dispersed particles do not settle out. Fog is a liquid - gas colloid, and homogenized milk is a liquid - liquid colloid. Windshield wiper fluid is a solution, and muddy water is a suspension.
3. Salt water is a solution. In a solution, the solute (salt) is dissolved at a molecular level and will pass through a filter. So the statement is false.

Answer:

17.
